You may need to add more if you have another algae bloom. Wait a week between applications and only treat a 1/2 or 1/3 of the pond at a time to recover oxygen levels.
How much Crystal Plex should I use?
Properly measure your pond to find the square acreage and average depth. One gallon of Crystal Plex, liquid copper sulfate solution will treat a surface acre 1 to 2 feet deep. Example: 1/2 acre pond 4 feet average depth, mix 1 gallon with 8 to 10 gallons of water. (Water is to help spread the product, not to dilute.) See labeled instructions for all application rates.

Yes, Crystal Plex is still effective in killing algae at the same application rate after it has been frozen. Freezing affects the residual control for Crystal Plex. Crystal Plex normally has a residual control of over a month. Frozen Crystal Plex will only have a residual effect in controlling algae for 3-5 days. When using frozen Crystal Plex be sure to shake well before diluting and spraying algae for control. I recommend using warm water to dilute the frozen Crystal Plex before spraying.
I used it In my 1/2 acre farm pond on Planktonic algae with In an hour turned dark put a trolling motor in to stir the water pond is beautiful again no algae. Been several weeks since it was used still no regrowth
I purchased this product in an attempt to deal with a major algae bloom in an approximately 1-1/2 acre pond behind my residence in southwest Florida. The product use information seemed to be directed at large scale use, perhaps spraying from a boat. Trying to determine the proper amount of concentrate to be diluted in a 2-gallon garden tank sprayer was much too difficult.
Spraying near shore from shallow water using the tank sprayer was the only reasonable option. Despite trying different dilutions and different spray densities, I found no detectable change in the sprayed areas of the algae bloom. I additionally tried spraying the diluted product into the plastic tub reservoir for a decorative outdoor fountain and found no decrease in the algae.
